Frequently Asked Questions
Q
What makes JF-303 sealant cure faster than standard sealants?
JF-303 is formulated with an advanced neutral curing system that accelerates the surface skin formation process, significantly minimizing exposure time to adverse weather conditions such as rain, dust, or humidity during the curing stage.
Q
Is JF-303 safe to use on coated glass and metal surfaces?
Yes. JF-303 uses a neutral curing mechanism, which means it does not release acetic acid or other corrosive by-products. It is safe for use on coated glass, anodized aluminum, stainless steel, and other sensitive building materials.
Q
Can JF-303 withstand extreme temperature conditions?
Absolutely. JF-303 maintains excellent elasticity and structural integrity across a wide temperature range — from as low as -50°C without becoming brittle or cracking, to as high as 150°C without softening or degrading.
Q
Is JF-303 suitable for curtain wall applications?
Yes. JF-303 is specifically designed to accommodate the normal expansion and shear deformation of curtain wall systems. It retains its performance characteristics under dynamic movement, making it an ideal choice for structural glazing and facade sealing.
Q
What types of building materials does JF-303 adhere to?
JF-303 provides excellent adhesion to a wide range of building materials, including glass, aluminum, stone, concrete, ceramic tiles, and most painted or primed surfaces — without the need for a primer in many applications.
Q
How does JF-303 perform against UV exposure and weathering?
JF-303 offers outstanding resistance to UV radiation, ozone, and moisture. Its silicone-based formulation ensures long-term color stability and prevents degradation caused by prolonged outdoor exposure, making it highly suitable for exterior facade and weatherproofing applications.
